, chassis bearings of automobiles, and it consiste in a-novel form of oil cup and a cooperative delivery nozzle connected to a lubrisant supply, as by a flexible conduit, and embodying an automatic shut olf valve which, when the nozzle is urged downwardly onto the cup, will open and permit the pas sa e of lubricant from the nozzle to the cup.

rimarily, the invention resides in improved means for the expeditious oiling oi bearings on an automobile chassis other than those that relate to the motor itself.

The invention further resides in an improved oill cup or nipple desi ned to replace and be substituted for ordginary oil and grease cups, and embodying a seat on which aV supply nozzle is engaged to eli'ect the opening of a valve within the nozzle and also to provide atight joint and seat between the cu and nozzle.

gurther, the invention is found to reside in an improved supply nozzle haring au inwardly opening valve for arrefping the How of lubricant except when the saine is unseated as by emragement withian oil nipple orcup.

Other objects will appear' as thc description progresses, and those features of construction, and arrangements und combina tions of, arts on which protection ist desired will be hereinafter described and claimed, reference being had to the accoinpauving drawings wherein:

Figures 4 and 5 are detailed sectional views on lines 4"-4 and 5-5, respectively, 55

of Figure 2, and

Figure 6 1s a' like view about on the plane' of line throu h a inodiied form.

The nl pple or or' cup 1 is preferably polygonal in cross section to receive an ordi- 60 nary Spanner wrench whereby its plug or lower lthreaded end 2 may be more easily connected to-a bearing. This threaded plug is counterbored to provide a seat for the ball check valve 3 which is backed by a 65 spring 4, the latter being'con'ned Within the countebore by the Vring nut 5. The interror of the cup is hollovir and provides a lcomparatively long' bearing surface for the Inte- 7o nozzle part hereinafter described. grally formed in the bottom of the cup is a beveled or conical seat 6 through which extends the inlet duct which is normally closed by the check Yvalve 3 to prevent back ilow of oil. The upper, opened end-of the cup is shaped on a bias and adapted to be lclosed hy a cup 7 .which is pivoted to the sides of the cup `for swinging rearwardly from olf the latter. The cap substantially conforms to the opp, bein open at the front and provided with. a ownwardly and outwardly rolled lip 8 on the front edgel of the top to snap or spring 4over the forward edge of l' the cup.

The nozzle 9, which has a flexible tube connection 10 to a, suitable receptacle or tank wherein the oil is contained under ressure, is designed to slidably and snug y t the long chamber of the oil cup or nipple.

The nozzle is tubular throughout so as to always be in direct communication with the hose connection l0, and adjacent its outer end said nozzle is formed with a tapered valve seat 11 for engagement by the conical valve l2. Said valve is spring-seated by coiled spring 13 compressed between a r1ng nut 14. threaded in the inner end of the nozzle, and the` upper guideextension l5 of the valve which is shown formed with a short stud to enter the lower end'of the 100 he had which permits of the readflow of oil thereby. such as is depicted at igure 6 wherein a cylinder guide 16 is formed with oil grooves 17 lengthwise thereof. The valve is also equipped with a lower guide extension 18 which fits a reduced axial bore. in the nozzle and extends to the upper or inner end of the flared seat 19 which opens through rthe outer end of the nozzle for engaging on the cup .seat 6, being slightly shorter than the latter as depicted in Figure 3. Immediately beneath the valve, the extension 18 is formed with a lateral port 2O leading to an axial duct 21 adapted to establish communication withI the outlet passage of the oil cup.

In practical use. the nozzle is inserted within the cup and the flared seat 19 engaged with seat 6, when, upon continued pressure exerted by the hand when pushing in the nozzle, the barrel extension 18, which may be considered as a valve, will be forced back- Wardly by said seat 6. thus causing the coni cal valve or part 12 to leave its seat 11, whereupon the oil will immediately under its pressure be forced around the sides of the guide 15 ,and valve 12, into the port 20. out through the port 21 a'nd into the cup inlet` and the pressure back of the oil will force down the ball check valve and discharge the oil into the bearing to be lubricated. As soon as the operator ceases pressing the nozzle inwardly the beveled part l2 will immediately. seat against 11. thus cutting ofi' the supplv of oil, and the ball check 3 vvillautomatically seat itself thus preventing the yoil from being forced back through the opening into the cup.- The ca p 7 is then closed to keep out all dirt and grit from the cup.

This same operation is repeated for cach bearing or oil cup. The nipple or cup l' is substituted for ordinary lubricant cups and bv the,employrnent of the cooperating nozzle the various bearings on an automobile chassis can be most Yempeditiously lubricated. Obviously. the cups can be attached to various other bearings Without departing from the spiritof the invention.

No claim is made herein to the combination of a suitable receptacle-or tank wherein tbe material is constantly maintained under pressureV and automatically released there- Afrom when the nozzle is brought into proper juxtaposition With the elements to be lubricated. Such matter is set forth and claimed in my copending application Serial No. 423.096, filed November 10, 1920.

What is claimed is:

1. In a. device for oiling the bearings of an automobile chassis. a cup having throughout its upper portion a fixed elongated opening While its lower part terminates in an exteriorly threaded plug also having an opening therethrough which communicates with the first named opening. an exteriorly beveled seat upstanding from the bot-tom of the cup and having an inlet port therethrough whereby conununication is established between said openings, a supply nozzle for dischargingV oil under pressure and adapted to be inserted in the cup, and a check valve in the nozzle arranged to be unseated by pressure of the nozzleagainst said seat, whereby the oil may be discharged into the bearings to be lubricated.

2. In a device for oiling the bearings of an automobile chassis, a cup having throughout its u per portion a comparatively large elongate opening While its lowervportion terminates in an exteriorly threaded plug having a com )aratively smaller opening therethrough Wliich communicates with the first named opening, an exteriorly beveled seat upstanding from the bottom of the c up and having an inlet port therethrough whereby7 communication is established between said openings, a supply nozzle for discharging oil under pressure and which is adapted to be inserted in the cup and which has a flared seat that enrrages over said beveled seat,`and a check va ve in the nozzle which is unseated by pressure of the nozzle against said beveled seat.
